Implantable cardioverter-defibrillator (ICD) is the therapy of choice in the prevention of  SCD. The ICD has been proven to improve survival among survivors of cardiac arrest, patients who are at risk of having one because of myocardial scarring and low left ventricular ejection fraction, and those with primary inherited arrhythmia syndromes. The insertion of an ICD is indicated for survivors of cardiac arrest due to ventricular fibrillation or hemodynamically unstable sustained ventricular tachycardia after the exclusion of any reversible cause. At present, there are no nationwide data regarding the prevalence of ventricular tachyarrhythmias requiring an ICD.

Radiofrequency catheter ablation (RFA) is an interventional cardiac electrophysiologic procedure that uses heat energy for definitive management of supraventricular tachycardias. It is a class I recommendation for chronic management of most supraventricular arrhythmias. No local data exist in the incidence hospitalization for SVT and utilization of RFA for this condition. The study aimed to obtain the prevalence of hospitalization of patients with supraventricular tachycardias where RFA is utilized, including the patients’ demographic profile, length of hospitalization, and mortality rate.

Symptomatic bradycardia, commonly attributed to sinus node dysfunction/ sick sinus syndrome, or atrioventricular (AV) blocks or conduction disorders from chronic  fascicular blocks, is treated by implantation of a permanent pacemaker. Despite it being a class  1 recommendation, there is a perception based on informal surveys that permanent pacemaker  implantation (PPI) is underutilized. The Philippines showed slow growth in the volume of  implantation from 1049 in 2015 to 1225 in 2016. The Philippine pacemaker data after 2016 are  incomplete and unreliable because of the lack of a national registry. It is the aim of this study to  ascertain the prevalence of cardiac arrhythmias requiring PPI and the volume of its utilization in the  Philippines. 

Radiofrequency ablation (RFA) is the recommended treatment of choice for supraventricular tachycardia (SVT), whereas implantable cardioverter-defibrillator (ICD) is recommended for patients at high risk for sudden death due to ventricular tachycardia/fibrillation. Radiofrequency ablation has been proven to improve the quality of life of patients with SVT, whereas an ICD has been shown to reduce mortality among patients at risk for sudden cardiac death. Both procedures are expensive and usually beyond the reach of the average Filipino patient.

Single coronary artery (SCA) is a rare congenital anomaly in which there is an isolated coronary  artery that arises from a single coronary ostium and provides coronary blood supply to the  entire myocardium. SCA is classified based on Lipton Classification which includes the origin,  branching pattern and course. We aim to present a rare case of congenital anomaly that  presented with atypical symptoms and to discuss the features and classification of a single  coronary artery.

A vast number of COVID-19 cases have been reported worldwide since  the initial outbreak in China, and the disease has since become a global pandemic. Knowledge  on this predominantly respiratory illness is evolving with studies suggesting myocardial injury  reflected by elevated cardiac enzymes portending to more severe disease. CT scoring indices  provide visual, semi-quantitative assessment of lung involvement and have aided in determining  extent of COVID-19 pneumonia but, none have been validated for prognostication. Establishing a  relationship between these non-invasive diagnostic parameters could provide timely identification  and proper allocation of limited medical resources to patients in need of more aggressive therapy. 

Intermediate-acting muscle relaxants have gained favor in fast-track cardiac  anesthesia since these are associated with early extubation. However, postoperative residual  curarization (PORC) still occur in the post anesthesia care unit. This study aims to determine the  occurrence of PORC among post-coronary artery bypass graft (CABG) patients in the surgical  intensive care units (SICU) of the Philippine Heart Center. 

Individualizing dose alteration of warfarin remains a challenge while optimizing  the benefit from warfarin and avoiding bleeding events. Hence, this study aimed to compare  the accuracy of bleeding risk scores in predicting bleeding events in patients with a mechanical  prosthetic valve.
